Abstract
The present paper illustrates an experimental analysis on the comparative analysis of air-conditioning energy savings of different green roof applications based on experimental measurements. Tests were carried out on nine different green roof samples, involving three types of growth media (lava, arkalyte, pumice) matched with three sedum types (kamtchaticum, spurium, sexangulare). Temperature readings at the bases of each sample were recorded for 32 months continuously at every 15 minutes. The data was processed and the heat gain of a sample building with each green roof application was calculated theoretically. The energy consumption comparisons showed that the right selection of growth media and vegetation can yield significant energy savings for air-conditioning applications.
